WEATHER-STRIP.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed October 27, 1917; Serial No. 198,822.

To all whom it may concern:

Be it known that I, LEWIS F. RoHDE, a citizen of the United States, residing at lVatertown, in the county of Codington and Stateof South Dakota, have invented certain new and useful Improvements in Weather-Strips, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in weather strips, and it is an object of the invention to provide a novel and improved weather strip adapted to be positioned adjacent the parting strip of a window frame or the like and which serves to efi'ectively protect said parting strip against wear incident to the movements of a window sash.

It is also an object of the invention to provide a novel and improved window strip which serves efiectually to prevent ingress of air or the like between a window sash and its co-acting frame.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved weather strip wherein certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood I will now proceed to describe the same with reference to the accompanying drawings wherein:

Figure 1 is a fragmentary view in horizontal section illustrating a weather strip constructed in accordance with an embodiment of my invention; and

Fig. 2 is a fragmentary view in horizontal section illustrating a weather strip con structed in accordance with a further embodiment of my invention.

As disclosed in Fig. 1 of the accompanying drawings F denotes a portion of the window frame provided with a parting strip P. Secured to the inner face of the frame F is the weather strip W formed of a fiat sheet of metal of predetermined length and having one marginal portion provided with the flange 1 extending the entire length of the strip W and substantially at r ht angl theret he fla g 1 co tes directly with the adjacent face of the parting. strip P. The strip W at a predetermined point inwardly of the flange 1 is folded upon itself to afford a longitudinally disposed flange 3 substantially in parallelism with the flange 1. The adjacent vertical stile 4 of. the window sash S is provided with a longitudinally disposed groove or channel 5 which is adapted to receive the flange 3. The groove or channel 5 is so positioned as to cause the inner face of the stile 1 to frictionally engage the flange 1 whereby it will be at once self-evident that the ingress or passage of air or the like between the stile 1 and the parting strip P is prevented. It will also be self-evident that the flange 1 will serve to protect the strip P against wear incident to the movement of the sash S. Furthermore it will be self evident that should the parting strip P be unduly worn before the weather strip is applied the flange 1 will co-act with said parting strip P in such a manner as to obviate the necessity of applying a new parting strip.

The inner longitudinal marginal portion of the strip W i returned upon itself as at 6 with the free longitudinal margin of said returned portion bent outwardly to afford the flange 1. The returned portion 6 of the strip W underlies the adjacent marginal portion of the parting strip P.

The form of invention illustrated in Fig. 2, is substantially the same as illustrated in Fig. 1, except that the flange 3 is positioned in close proximity to the flange 1". Snugly fitting between the flanges 1 and 3 is a metallic plate 7 secured to the inner face of the vertical stile 4 of the window sash and this plate overlies a longitudinally disposed recess produced in the inner face of the stile 4' which snugly receives the flange 3". In this latter form it will be noted that metal contacts with metal whereby the life of the parting strip is materially prolonged as wear upon the parting strip and the sash is substantially entirely eliminated.

From the foregoing description, it is thought to be obvious that a weather strip constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is usceptible of some change and modification without ma rial y departing from h prin- I do not Wish to be understood as limiting" myself to the precise arrangement and for- 'mation of the several parts herein shown in carrying out my invention in practice eX- cept as hereinafter claimed.

I claim:

In combination With a \ViDClOW frame provided with a parting strip and a sash coacting therewith, a Weather strip comprising an elongated sheet of metal secured to the frame and provided with a marginal flange contacting with the parting strip, and providedavith a second flange in parallelism with the first named flange and spaced relative thereto, said sash being provided With a channel to receive the second named flange, said channel being so positioned 1n the sash as to cause the portion of the sash between both of the flanges to frictionally contact With the first named flange, the longitudinal marginal portion of the strip provided with the first named flange LEWIS F. ROHDE.
